DESCRIPTION
The 2N/SST5484 series consists of n-channel JFETs
designed to provide high-performance amplification,
especially at high frequencies up to and beyond 400 MHz.
The 2N series, TO-226AA (TO-92), and SST series, TO-236
(SOT-23), packages provide low-cost options and are
available with tape-and-reel to support automated assembly
(see Packaging Information).

b. Pulse test: PW v300 s duty cycle v3%.
c. This parameter not registered with JEDEC.
d. Not a production test.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
